钻孔灌注桩后注浆技术在太原地区粉土中的应用

摘要

以鼎太风华项目为依托，对场地的工程地质概况作了分析，选择了钻孔灌注桩后注浆桩基方案，并对桩基进行了计算设计，阐述了桩基的施工要点、检验要点及后压浆提高单桩竖向承载力的原理，为推广应用该技术奠定了基础。%Based on Dingtaifenghua Program,the paper analyzes its engineering geology survey of the site,selects the bored pile’s post-grouting pile foundation scheme,has the calculation design of the pile foundation,and illustrates the construction and inspection points for the pile founda-tion and the principle of the post-grouting to improve the pile vertical loading capacity,so as to lay the foundation for the technical extension.
